The invention discloses a preparation method for functional finishing of wool fabric through plant pectin. The method comprises the following steps that 1, a pectin finishing solution is prepared, the plant pectin extracted through the method is fully dried at the normal temperature, the dried plant pectin is squeezed into pectin powder, pectin of a certain weight is obtained through weighing and put into a measuring cup, then distilled water of a certain volume is obtained through weighing and poured into the measuring cup containing the pectin, the mass fraction of the pectin in the prepared finishing solution ranges from 3% to 6%, the bath ratio of the finishing solution is 1:40-50, and finally the pectin and the distilled water are heated in a set thermostat water bath and stirred continuously by a glass bar for 30-40 minutes until the pectin is completely dissolved; 2, the pectin solution is finished, after the pectin is completely dissolved, prepared wool fabric is scoured and then completely soaked into the finishing solution, timing is conducted when the wool fabric is completely padded, the wool fabric is continuously stirred by the glass bar, after about 30-40 minutes, the wool fabric is taken out, washed 2-3 times through clear water and twisted dry, and the wool fabric is placed in a fixed-temperature and fixed-humidity laboratory and naturally dried.

The present invention is a moisture-proof method for coating the surface of wooden materials. The process steps are as follows: 1. cleaning the surface of the wooden material; 2. placing the wooden material after the surface cleaning treatment in a vacuum coating machine; The waterproof coating material is evaporated into a gaseous state in the evaporation chamber, and then enters the cracking chamber, where it is cracked into active monomers with reactive characteristics; this active monomer is gradually deposited on the surface of the wood material in the deposition chamber to aggregate and crystallize; forming a thickness of 1~5um Highly cross-linked pinhole-free polymer film waterproof membrane layer. Advantages: reduce the deformation of wood materials after moisture absorption, and greatly improve the waterproof and moisture-proof performance of materials. Maintain the unique color, mechanism and performance of the wood itself, improve the moisture-proof, mildew-proof, anti-corrosion, and moth-proof properties of the material, and use wood resources more effectively.

The invention relates to a waterproof, fireproof, and moth-proof plant fiber and its molding process, belonging to the technical field of building material fillers. The plant fiber includes the following components in parts by weight: 50-60 parts of wheat straw, 10-20 parts of peanut shell powder, 5~20 parts of glutinous rice-starch binder, 20~22 parts of calcium hydroxide, 3~10 parts of paraffin waterproof powder and 1~5 parts of fireproof fiber; with wheat straw and peanut shell powder as the base material, and for wheat straw, Peanut shell powder is subjected to anti-corrosion treatment, compounded with glutinous rice-starch binder and paraffin waterproof powder, which can firmly bond wheat straw, peanut shell powder and other fillers, and form a hydrophobic layer on the surface of plant fibers to prevent moisture from clouding Wet the surface of the plant fiber, and add the fire-proof fiber to prepare the plant fiber with functions of waterproof, fire-proof and moth-proof.
